in industrial applications, most materials are exposed to wear and friction because multiple conditions are used. however, the tribological properties of these materials can be improved with different techniques. one such technique that improves the frictional property of a surface is the use of self-lubricating coatings. in this study, multicomponent coatings of nominal composition cu-ni3al-mo...

Here, we report the use of amine-terminated poly(amidoamine) (PAMAM) dendrimers as adhesion promoters between vapor-deposited Au films and Si-based substrates. This method is relatively simple, requiring only substrate cleaning, dipping, and rinsing. Proof of concept is illustrated by coating glass slides and single-crystal Si wafers with monolayers of PAMAM dendrimers and then evaporating adhe...

In the plastic molding industry, plastic parts like pager and handphone cases, plastic containers, etc. are formed in a mold by applying temperature and pressure. The transfer molding is the standard workhorse for the electronics industry. Although the transfer molding is widely used, it is far from being optimized. Mold sticking is a serious practical problem in this industry. A solution to th...

The problem of calculating the required adhesion strength and accuracy measuring adhesive/cohesive thermally sprayed coatings (thermal barrier, electrically insulating, irradiation) on a cylindrical test specimen is practical interest from point view improving reliability highly loaded parts internal combustion engines agricultural machines, various aerospace nuclear industries. There have been...

In this paper, the carbon dioxide (CO2) plasma-assisted method was firstly developed for preparation of dopamine coating polydimethylsiloxane (PDMS). The PDMS films were pre-treated by CO2 plasma at power 30–60 W 5–10 min and then modified 18 h. results showed that many polar groups such as C-O bonds, C=O O-C=O bonds introduced into surface films, which successfully promoted formation poly(dopa...

Hydrogen free diamond-like carbon (DLC) coatings have been the subject of investigation all around the world for the last 30 years. DLC, due to its unique properties such as: chemical inertness, high mechanical hardness, high electrical resistivity combined with a characteristics of a wide band semiconductor, is a very promising material for biomedical, mechanical and electrical applications. O...

BACKGROUND AND AIMS Since high-density lipoprotein (HDL) has pro-endothelial and anti-thrombotic effects, a HDL recruiting stent may prevent restenosis. In the present study we address the functional characteristics of an apolipoprotein A-I (ApoA-I) antibody coating in vitro. Subsequently, we tested its biological performance applied on stents in vivo in rabbits. MATERIALS AND METHODS The imp...

A new type of titanate nanotube (TNT) coating is investigated for exploitation in biosensor applications. The TNT layers were prepared from stable but additive-free sols without applying any binding compounds. The simple, fast spin-coating process was carried out at room temperature, and resulted in well-formed films around 10nm thick. The films are highly transparent as expected from their nan...

Nontoxic, low surface free energy silicone coatings having reduced biofouling adhesion strength have been developed as an alternative to antifouling paints. Silicone coatings permit macrofouling to adhere; however, fouling can be removed easily by water pressure or light scrubbing. One of the current methods used to evaluate the performance of non-toxic silicone foulingrelease coatings relies h...

Bioinspired Polymeric Coating A universal and facile multifunctional biomimetic coating with excellent self-adhesion, lubrication, sustained drug release properties is designed in article number 2200561 by Haimang Wang, Xin Zhao, Hongyu Zhang, co-workers. It based on mussel-inspired catecholamine chemistry articular cartilage hydration which could be modified onto different substrates of biomed...
